  abstract = {{L}ocal people's perceptions of cultivated and wild agrobiodiversity, as well as their management of hybridization are still understudied in {A}mazonia. {H}ere we analyze domesticated treegourd ({C}rescentia cujete), whose versatile fruits have technological, symbolic, and medicinal uses. {A} wild relative ({C}.amazonica) of the cultivated species grows spontaneously in {A}mazonian flooded forests. {W}e demonstrated, using whole chloroplast sequences and nuclear microsatellites, that the two species are strongly differentiated. {N}onetheless, they hybridize readily throughout {A}mazonia and the proportions of admixture correlate with fruit size variation of cultivated trees. {N}ew morphotypes arise from hybridization, which are recognized by people and named as local varieties. {S}mall hybrid fruits are used to make the important symbolic rattle (maraca), suggesting that management of hybrid trees is an ancient human practice in {A}mazonia. {E}ffective conservation of {A}mazonian agrobiodiversity needs to incorporate this interaction between wild and cultivated populations that is managed by smallholder families. {B}eyond treegourd, our study clearly shows that hybridization plays an important role in tree crop phenotypic diversification and that the integration of molecular analyses and farmers' perceptions of diversity help disentangle crop domestication history.},
